I've installed a LOT of wiring harnesses on trailers, made pigtails for the truck to trailer and am generally happy with Hopkins quality products. BUT I am not happy that this pigtail uses colors for the wires that are NOT universally standard. IF I had hooked this up by the proper color code, it would not have worked. IF there had been a color code provided with the cable it would have been an easier installation. As it was I had to wring out each one separately. On a positive note, the LEDs are a nice touch.



by:

Why doesn’t the 7 way cable have standard color coded wires ?



by:

I purchased this to replace the one on my 5th wheel RV that had a bad onnection. I have been using it for a year and at 22 RV parks to date as a full time Rver. It is still working flawlessly.



by:

Fits nice and snug in the socket I think it's going to really do the job. This is for a boat trailer that in and out of the saltwater. I'm real curious to see how this holds up. This is the first time I've tried a rubber molded trailer wiring.



by:

Great product. Wires matched the colors in my control box. Made switching plug a snap. Only wish it came with ring connectors.



by:

Solidly built, high quality materials. 1st time amateur wiring of a trailer. Im going to study some "how to" videos. But I've got the right materials for a successful project.



by:

I like the lights on the plug- saved me a midnight question about whether my trailer or tow vehicle had a fault.



by:

I ordered one Monday morning and received it on Tuesday afternoon. Everything was in the box and in excellent shape. I got everything installed the same evening following the instructions on the website. I tested it and everything works correctly. Thankyou etrailer!!!



by:

Excellent product. Indicator lights immediately inform you of a problem should one occur, as well as indicating specifically which wire is causing the problem.



by:

Awesome!! Locally they wanted $75 I paid less, exactly as described. Combined with a few other items I needed and got free shipping!! Product was exactly as described.



by:

So far so good.



by:

I like the light that tells you it’s wo rking



by:

Seems good, have not installed yet

by:

Received cable fast. Looks like it will work great, putting it on next week

Working Great.

  • Parts to Convert Surge Brakes to Electric Brakes on Boat Trailer With 3,500 lb Axles
    Thanks so much for that info, and we can get your boat trailer set up with electric brakes. Since you had an idler hub you will need a hub and drum for electric brakes, and with the bearing numbers you gave, that means you have 3,500 lb axles. That said, here is everything you'll need to make the conversion: - Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter - 5 on 4-1/2 - Galvanized # AKHD-545-35-G-K - Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand...

  • 10 Long 7-Way Cable With Double Ended Trailer End Connectors
    I have a couple options for you as we do not have a double ended 7-Way Molded Trailer Wire Connector in a 10' length. First you can take a 7-Way Molded Connector w/ 10' Cable # 50-67-005 and add a 7-Way RV Style Trailer Connector # A7WCB. Or you can connect 2 Hopkins 7-Way RV Style Connector w/ Molded Cables # HM20086 together if you prefer to have the molded and sealed ends.

  • What to Check When There is No Power to the Right Side Blinker and Brake Light?
    The white wires will indeed need to be grounded. This should be done with both lights. If this does not get the lights working properly, you will need to use something like the # PTW2993 to test several things. First, you will need to check the plug on your vehicle to make sure all the ports are working properly. If you have a 7 Way connection, the 3 o'clock position will be the right turn signal and right brake signal. If there is no power, you will need to then check the wire on the...

  • How to Trouble Shoot Brake and Turn Signals Not Working On a Trailer
    This can be caused by a few things. First and foremost, you will need to check a couple fuses to make sure they are still in good condition. Under the hood of your 2018 Toyota Tundra, you will want to check the fuses in positions 6 and 37. Then you will need to check the cluster under the instrument panel for fuses 20 and 22. These can be confirmed in your owner's manual, but these are responsible for the towing lights. If one or more have blown, it will definitely cause the issue you are...

  • Should Junction Box be Used For Adding 7-Way & Wiring to Trailer
    For adding wiring and a 7-way to your trailer, a junction box and 7-way connector is absolutely the way to go, because it is the easiest way to connect your wiring. The best option for that is the following: - Junction Box - 7 Terminal # 3375601100 - 7-Way RV Style Connector - Trailer End 6 ' Long # HM20086 or 8' Long # H20046 If you need added components for install such as a wire tool, zip ties, circuit tester, butt connectors and more, you may want to consider getting that in one...

  • Parts to Convert From Disc Brakes to Electric Trailer Brakes
    You can convert from hydraulic disc brakes to electric brakes, though an electric over hydraulic actuator won't be used. Electric trailer brakes fit inside a trailer hub and drum, so the first thing you will need to do is remove your idler hub and rotor and get the correct hub and drum. To get the correct hub and drum, you need to know the weight rating of your axles, and also what bearings your current hub has. You will need to take apart your current hub assembly and look at the bearings...

  • What to Check When the Light on a Trailer are Not Working
    Lights not working on a trailer can be caused by quite a few different things. The first thing to check is all your grounds. A bad ground can cause any number of things to happen and is always a good place to start. From there, you will need to check the towing fuses to make sure they are still in good condition. You will need to confirm which these are in your owner's manual. If one or more have blown, it will definitely cause the issue you are having. If all the towing fuses look good,...

  • Can Trailer 4-Way be Wired to Activate Trailer Brakes
    A 4-way is not able to activate trailer brakes as it is for lighting only, so it doesn't have the ability to carry the signals to your brakes. So what you'll need for your trailer is a junction box and 7-way: - Junction Box - 7 Terminal # 3375601100 - 7-Way RV Style Connector - Trailer End 6 ' Long # HM20086 or 8' Long # H20046 You'll wire your brakes (as well as your lights) directly to the junction box, which the 7-way is hooked up to. What you will need is brake wire, which is available...
